Actually, I hadn't look at the build log. I also have the same thing in 
the build log. However, I am not sure we want to fix that. Here what 
this option does:

  Specifies maximal overall growth of the compilation unit caused
  by inlining.  This parameter is ignored when -funit-at-a-time
  is not used.  The default value is 50 which limits unit growth
  to 1.5 times the original size.

I am not sure we want to have a so big increase in the file size.
